Highway 47, Fern Hill Road and Maple Street Intersection

We will design a traffic signal to address safety concerns at the Fern Hill Road - Maple Street and Highway 47 intersection.

Maple Street - Fern Hill Road crosses Highway 47 where the highway curves and speed limits increase.

The proposed design includes a traffic signal with pedestrian crossings. We have included a right-turn lane from Highway 47 to Fern Hill Road.
